S365 and the 270 can be a problem child at best. DaleSH (Gunsite) describes the effect as a "turbo boost" when pressures start to exceed 50 000 psi. Loading near the top therefore requires careful charges to get the best performance.

I did once try S365 in my .303. With the wind from the front, having partial burnt and unburnt powder blow into your face is not a pleasant experience.

365 is in stock at my local. I'm in two minds about giving it a bash. One mind says 'why bother with load dev you'll never get another tin' and the other 'but its soo cheap'. My 270 win which I have owned for 5 years or so has never tasted 365 as it's been unobtanium since I got it.

First, put away the S365.

Driepoot will be along soon to give you the rest.

Agree, S365 is for 30-06, 270, 7x64 etc.

S341, S335, S321 goes for 308.

Some of the imported powders are said to be more stable.
